The Formation Mechanism of Oestrogenic Hormones

摘要: Summary. By means of polarisation optical and histochemical methods we have succeded in demonstrating the presence a sterol cholesterol type – probably indentical with interstitial gland theca interna rabbit ovary. The amount this varies according to sexual phase: during oestrous, pregnancy pseudo-pregnancy it is found be stored cells large amounts, while immature or anoestrous ovaries on other hand show either none only very small amounts. The majority present ovary form ester. It biologically inactive. In case forced secretion oestrogenic hormones (coitus, injection gonadotrophic hormone) mobilised from ovaries. If an intense stimulation applied, mobilisation may completed within course some few hours, falls high low values. This indicates that demostrated intimately connected formation hormones. The results obtained our investigations suggest precursor substances formed
